Abstract
A 53-year-old male from Atsugi City, Japan, presented with an elongating serpentine erythema on the right side of his abdomen. He had eaten Watasenia scintilloans (Hotaruika) approximately 10 days before the skin lesion developed. A laboratory examination revealed mild eosinophilia, while no serological reactions were positive to Gnathostoma or any other parasites. Considering the foodstuff which the patient had eaten, we diagnosed this lesion to be creeping disease which was probably caused by a nematode belonging to the suborder of Spirurina.
